Abstract: Certain aspects of the present disclosure provide techniques for improving time division duplexing (TDD) downlink-uplink configuration for new radio (NR) operation with large timing advancements (TAs). An example method by a user equipment (UE) includes transmitting, to a network entity, an indication of a timing advance (TA) value; receiving, from the network entity, information indicating a set of downlink slots of a time division duplexing (TDD) pattern that is dynamically restricted from being scheduled for the UE, wherein the set of downlink slots is based on the TA value; and receiving, from the network entity, downlink transmissions in downlink slots of the TDD pattern except in downlink slots included in the set of downlink slots.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication that the UE is to perform radio resource management (RRM) measurements at a first periodicity. The UE may identify an RRM measurement relaxation grouping to which the UE belongs based on at least one of a mobility of the UE or a location of the UE within a cell, such as whether the UE is near a cell-edge, or whether the UE is stationary or moving in accordance with low-mobility, or a combination thereof. The UE may determine a first relaxation parameter from a plurality of relaxation parameters based on measurement relaxation criterion associated with the cell, where the plurality of relaxation parameters may be associated with the RRM measurement relaxation grouping. The UE may perform the RRM measurements at a second periodicity that is based on the first relaxation parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may support configured grant (CG)-small data transmission (SDT) procedures. To improve CG-SDT, the UE may validate measurement resources for timing advance (TA) validation and CG resource validation. The UE may receive a radio resource control (RRC) release message indicating CG resources and information that may be used for TA and CG resource validation, and the UE may receive measurement information based on one or more reference signals. In some cases, the UE may validate the measurement information and use it to perform a TA command (TAC) validation procedure. In some other cases, the UE may validate the measurement information and use it to perform a communication resources validation procedure. While in an inactive state, the UE may transmit an uplink communication using the validated TA and the validated communication resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a user equipment (UE), which may include a reduced capability (RedCap) UE, and a supporting cell. The UE may receive a synchronization signal block (SSB). The UE may receive a configuration of an active downlink bandwidth part (BWP) that is not configured with a SSB. The UE may tune, from the active downlink BWP to a different frequency for a layer 1 (L1) measurement gap defined by a L1 measurement gap configuration. The UE may perform a L1 measurement of the SSB on the different frequency during the L1 measurement gap. The UE may be a RedCap UE, the active BWP may be for RedCap UEs, and the SSB may define an initial BWP for the RedCap UEs and non-RedCap UEs, and the different frequency may be the initial BWP.
